Rated 5 out of 5 by Fantastic Pressure Washer!!! First one owned, but very satisfied, all positive comments justified, tested and proven by me. September 20, 2016
Rated 5 out of 5 by Excellent tool added to garage First pressure washer I have ever bought. I did plenty of research and said let's try this one. Well all the reviews were right. This is a quality machine that is priced well for the homeowner. It allows me to get different things like the house and concrete and deck looking like new every year! Thankyou for a above average product for a smaller amount of money. September 16, 2016
Rated 5 out of 5 by Excellent product My power washer is awesome starts first pull,easy to use and move . September 16, 2016
Rated 5 out of 5 by Excellent Product and Excellent Value My 3rd PW over past 8 years. This by far exceeds the other manufacturer's models I have used. Just prepared my home for painting with an initial cleaning and then using higher pressure nozzle to remove peeling paint from porch columns and it performed perfectly. Additionally I didn't notice my arms or shoulders being as strained as experienced in previous models. At 70 years old I look for ease of setup and ease of use and the Generac certainly met my expectations. I have even recommended this model to two neighbors who stopped by to check on my labors. They were also impressed by its quiet operation. Good job for an USA product. Thanks, Generac! September 14, 2016
Rated 5 out of 5 by Great product Great product used for a variety jobs from gutters, concrete , to house washing. September 14, 2016
Rated 5 out of 5 by Great pressure washer I had originally purchased this to do odds around the house & wash our vehicles. I didn't know back when I got it I would REALLY be needing it! I picked up a RZR UTV & each time out it gets real muddy. I add some pressure washer safe soap to the tank, spray it down on low then bump up to the green tip to get it really cleaned of. Its saved me $$$ trying to do this at a car wash that allows something this dirty, trust me! I've had it for a little over 1 year & even after sitting over the winter, still starts on 1 or maybe 2 pulls. September 14, 2016
Rated 5 out of 5 by First Power Washer - Love it !!!!!!! After much research and review, we purchased the Generac 6602 power washer. Given I have just retired; my first project was to power wash our arbor and prep for staining. Assembly was easy and the washer started with the first pull. The power washer comes with a power dial that can be adjusted for - car washing, house cleaning, fence cleaning, and brick cleaning. There are three pressure nozzles - Red for blast pressure, Green for wash and Black for detergent use. I used the fence setting for the Arbor; and adjusted nozzle types as needed. The power has a chemical tank that detergent can be used with the black nozzle. I now have about 12 hours of use with the power washer and have had no issues. September 7, 2016
Rated 5 out of 5 by Generac Pressure Washer This pressure has been a great all around the house tool. My wife actually purchased this unit and I was worried about it not having enough pressure and boy was I wrong! This washer has exceeded my expectations August 17, 2016
